Assessment scale for behaviour in bulfighting cattle (EBL 10). Reliability and validity studies

Abstract

Our intention is to objectively assess the behavior patterns related to bravery in bullfighting cattle by means of a scale devised for this purpose. Reliability and validity studies have been carried out. This instrument will allow researchers to analyse inherited behaviour characters, permitting breeders to select in a more objective and systematic way. The evaluation scale of bravery in Fighting bovines, EBL 10, has been constructed. A glossary has also been developed with the distinguishing definitions of the ten dimensions dealt with, as well as a set of objective indicators for each dimension. A feasibility and validity study of the scale has been undertaken, assessing a sample made up of 380 bulls" behavior during a bullfight. Previously, a reliability study was carried out by two evaluators in a sample of 116 cows during a practical bravery test, (tienta). The scale (EBL 10) is a valid and reliable tool for standard behavior assessment related to bravery in fighting bovines and may be useful for both researchers and breeders alike.
